ER,
I suspect the candidate parameters could still be adjusted to different numbers, however are constrained by management to the numbers you state.

I recall one of my colleagues getting a hit on candidate #29. I used to kid him that if he only coded his latents better, hits would be higher on the list. In reality, placement of a correct candidate in a list is dependent on several variables, including system capability, quality of the database and coding, as well as skill of the examiner/operator.

I have no doubt that search & matching algorithms have improved and been refined, however many databases still contain converted inked fingerprints from the 1970's and prior. Has the coding on those converted inked fingerprints been upgraded along with system upgrades?

Hi Pat and Bob,

I realize that I'm a little slow on the draw for this thread but I'm not on here that much these days. Anyway, I thought I might chime in since we all work/worked with the same AFIS system. It is my understanding that our 'new' Metamorpho system and AZDPS has the capability to maintain all of the candidate lists. We are an agency that has also maintained all candidate lists regardless of the 'positive/negative' results as part of our documentation. However, AZDPS has assured us that as of June 2007 the candidate lists are maintained for every search and therefore we are considering the discontinuation of that policy. If we go this route, we would probably still maintain the candidate lists for 'hits' but only because if a candidate list is ever requested by the courts it's most likely going to be on an AFIS 'hit' and that way we would have it 'readily' available. Having said that, it's been many years since a candidate list has been requested from us.
